APPARATUS FOR MAKING CONCRETE CISTERNS OR TANKS.

SPECIFICATION forming part of Letters Patent N 0. 775,290, datedNovember 15, 1904.

To (all whmn it Uta/y comm/It:

Be it known that I, J OHN IVEARTH, a citizen of the United States,residing at Ames, in the county of Story and State of Iowa, haveinvented a new and useful Apparatus for Making Concrete Cisterns orTanks, of which the following is a specification.

The objects of my invention are to provide frameworks between which aplastic material may be placed and maintained until the plastic materialhas become hardened sufficiently to make a solid wall sufficient for acistern or tank, and, further, to provide a framework of this kind whichcan be easily removed for subsequent use after the material has becomehardened, the material object being to provide means of this kind formaking cisterns or other tanks.

My invention consists in certain details in the construction,arrangement, and combination of the various parts of the device wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which Figure 1 is a vertical sectional view of the cisternas it is being formed and maintained in position between the parts ofthe device. Fig. 2 is a vertical sectional view of the device forshaping the upper portion of the cistern. Fig. 3 is a vertical sectionalview of the device cut on the line 3 3 of Fig. 1. Fig. 4. shows inperspective the complete cistern after the retaining devices have beenremoved. Fig. 5 is a detail view of a part of the framework, showing theway in which the slats on each part are held together. Fig. 6 is a planview of the frame for making the top portion of the cistern.

Referring to the accompanying drawings, 1 have used thereference-numeral 10 to indicate the bottom portion of the outsideframe, which is made of a single flat piece of board or a number ofboards attached to form a circular flat surface upon which the cisternis designed to rest. Detachably connected with this portion 10 by meansof the hooks and eyes 11 is a framework 12, composed of a large numberof slats 13, which are tapered from their exterior surface to theirinterior surface to form a semicircular part, of which there are two ormore in number, to form the circular framework 12. Each of these slatsis attached to the one next to it by means of the screws 14, so thatthis framework 12 is rigid. The bands 19 and 20 are passed around theoutside portion of the parts 15 and 16 to hold the parts of theframework in position. The ends of the band 19 are held together bymeans of the bolt 21, and the ends of the part 20 are held together bymeans of the bolt In constructing the cistern the bottom portion 10 isplaced on the ground, and the framework 12 is attached to the bottom 10by means of the hooks and eyes 11, and the bottom of the cistern 23 ismade by spreading the mortar over the bottom 12, as shown clearly inFig. 1 of the drawings. I have provided an inner framework comprisingthe two semicircular portions 24 and 25 and the bands 28. The innerframework is constructed in the same way as the outer framework 12,except that it is smaller in size and wedges 26 and 27 provided to bemoved inwardly to remove them from between the portions 2% and 25. Theportions 24-. and 25 are placed on top of the bottom 23 and between theparts 15 and 16. The mortar or other plastic material is then filled inbetween the inner framework and the outer framework to form the sides 29of the cistern. The entire framework is left in this position until thesides 29 and the bottom 23 have become sufficiently hardened.

To form the cover, I have provided a funnel-shaped portion comprisingthe two parts 30 and 31, which are held in position relative to eachother by means of the parts 32 and 33. A smaller substantiallyfunnel-shaped portion 3 f is provided, so that when the plastic materialis placed between the part Set and the parts 30 31 it will form the topportion 35 of the cistern. This plastic material is allowed to becomehardened in this framework for the cover while the body portion of thecistern is becoming hardened between the framework above described.\Vhen the plastic material is sufiiciently hardened, the wedges 26 and27 are removed from between the semicircular portions 24: and 25, andthis will allow the removal of these semicircular portions from theinterior of the material, and they can be used for making any cistern.The bands 19 and 20 are then removed from the outer framework. Theseportions are then removed, and the cistern stands in the position shownin Fig. 4c of the drawings. The bands 32 and 33 are then removed fromthe semicircular portions 30 and 31, and these portions are removed fromthe top portion 35 of the cistern. The funnel-shaped portion 34 is thenremoved from the top portion 35. The top portion 35 is then placed uponthe upper portion of the sides 29, as shown in Fig. 4E, and the topportion and the sides are sealed together by mortar. The cistern is thencompleted. Earth is then filled around the outside of the cisternproper, and the cistern is then in readiness for use.

By this construction the cost of making the cistern is considerablyreduced and an absolutely waterproof serviceable cistern is provided. Bythe use of this method the materials for making the cisterns can be usedagain in making cisterns.

In practical use the cistern is made in the above-described framework,and after the cistern proper has become hardened the framework isremoved, and the cistern can be then placed in a hole dug for it, sothat it is practical to use my cistern in very wet places and wherebrick cisterns could not be easily constructed. The advantage of thisdevice is self-evident, owing to the fact that a cistern may beconstructed at any place prior to the digging of the hole for thecistern, and the completed cistern can be moved to the desired locationand lowered into the hole dug for this cistern.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States therefor, is-

1. In a device of the class described, the combination of a bottomportion, a framework detachably connected with said bottom portioncomprising a number of parts designed to be held in position relative toeach other by means of detachable bands, a second frameworkcomprisinganumber of parts held in position relative to each other bybands, wedges designed to be placed between the parts of said secondframework which are capable of being moved inwardly when it is desiredto take the framework down, said second framework designed to be placedon the interior of the first framework so that mortar or other substancecan be placed between the outer portion of the second framework and theinner portion of the first framework for holding the mortar while it isbeing formed, a two-part funnelshaped portion,

means for holding the parts of said funnelshaped portion together, asecond funnelshaped portion designed to be placed inside of saidtwo-partfunnel-shaped portion so that mortar can be placed between saidparts while it is being formed, for the purposes stated.

2.. In a device of the class described, atwopart framework comprising aseries of tapered slats, means for securing these slats together forforming each part of this two-part framework, a wedge designed to bemounted between the parts of said framework and a detachable band forholding said parts together in position relative to each other when thewedges are between the parts of said twopart framework.
